DRIVER FOR SPINNING SPOOLS.

Application filed October 26, 1922. Serial No. 597,037.

To all whom it may concern.

Be it known that I, JOHN NORMAN ANDER- SON, acitizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Drivers for Spinning Spools; and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

The present invention relates to an improvement in drivers for spinning spools, bobbins and the like.

The object of the invention is to improve the construction and reduce the cost of drivers and to the above ends the present invention consists of the driver for spinning spools hereinafter described and particularly defined in the claim.

In the accompanying drawing illustrating the preferred form of the invention Fig. 1 is an edge view of a driver blank; Fig. 2 is an elevation of the same; Fig. 8 is a plan of the. completed driver; Fig. 4 is afront elevation of the same, and Fig. 5 is an end elevation.

Spools for use in twisting and spinning are driven by dogs on the spindle or spindle whirl which enter recesses in the spool heads. The Dixon driver comprises a drawn metal lining for the opening in the spool head which forms a wear piece constituting a protection to the surfaces of the spool head otherwise directly engaged by the spindle and driving dogs. This driver is ordinarily circular in shape with enlargements on opposite sides of the axis to receive the driving dogs. The making of these Dixon drivers is expensive by reason of the large numher of operations which are necessary in order to draw the driver from the sheet metal and in addition because of the large amount of waste incident to this method of manufacture. According to the present invention the driver consists of a strip of sheet metal, bent to the required form and having the ends of the strip united together to form a substantially continuous driver. The outer surface of the driver is provided with lugs or projections which enter the wood of the spool head and serve to hold or secure the I driver in place therein. The illustrated embodiment of the invention is described as follows: First referring to Figs. 1 and 2 it will be seen that the blank 10 of which the driver is to be formed consists of a strip of sheet metal provided on one end with a dovetailed tongue 11, at the other end with a dove-tailed recess 12. The sides of the strip are provided with punched projections 13 which are formed to project from the surface of the blank which afterwards is to form the outside surface of the driver. These projections taper from one end to the other so as to facilitate forcing the driver into the spool head. The driver blank 10 having been stamped out of a strip of sheet metal is bent to the form of a single closed curve, that is to say, a curve which does not cut itself at any point, as illustrated in Fig. 3, the ends being then interlocked. The driver is then ready for the market. It is not material what means are provided for uniting the ends of the strips, any interlocking arrangement being within the purview of the invention. The important feature of the invention resides in the economy of manufacture because it is apparent that by using the strips in the form illustrated there is no waste, the cut separating one strip from the next, forming at one time the recess on the one end and the tongue at the other. The'projections taper from side to side of the driver and thereby enter the wood of the spool head with ease and pass beyond the surface of the spool head and thereby tend to hold the driver in place therein. The cost of manufacturing drivers for spinning spools, as they may be called, of the form of thepresent invention, is only a fractional part of the cost of making drivers according to the method formerly practiced.

Having thus described the invention what is claimed is: l

A driver for spinning spools formed from a flat strip of sheet metal having a series of projections along the side and bent into a single closed curve of non-round form with the ends of the strip united together.
